With reference to the drawings, .10 designates the roll standbeam'of' the spinning. frame which is'usualIy of angleiromformation as shown in Figures 1, 5, and 9. Rolf-stands" designated generally 11 are positioned at intervals-along this rail and support the. bottom front roll-12," the bottom back roll 13, and the intermediate assembly of top and bottom rolls designated as a unit 14"-'(Figure-9). The bottom rolls i2 and lit-extend from one'roll stand'to another and areprovided at spaced locations along'their' length with a ribbed surface 15. Tandem lengths of bottom rolls are keyed together throughout the length of the frame and are driven from i one end of the frame in a usual manner.

Thetop 'rolls'which engage with the bottom rolls 12 and- 13each comprise an arbor 16 (Figure 8) which carries -'cots-17'17' at spaced intervals on the arbor. The arboris'reduced as at 18 at a point between the arbor may extend beyond the cots, but as the extension which usually comprises gudgeons which are engaged by-cap bars are not a part of this invention, it is immaterial'whether the arbor extends beyond the end surface ofthe cots or not so far as the functioning of this invention'is concerned.

The supporting posts are designated 25 and are located atintervals along the rear of the frame, being secured on the rod 26 extending lengthwise of the frame, which their'assembly wwith' the runit'unless intentionally removed 51 rod-is held rigid With the am and the posts are held rigid with the rod by 'pin 26a While a screw 26' extends through the portion 7% into the bottom of the port.

Anxarm designated generally 20 (Figures 2 and 3) together with a front top roll and a back top roll, the clearers for these rolls, and the mounting means therefor constitute what we term a unit assembly. After detaching the' stirrup' from'this unit assembly, it may be removed bodily from the frame or it may be swung upwardly about a supporting post 25 which serves to mount and lock it in position. r e 1 r This arm 20 is generally channel shape in cross section and comprises a top wall 21 and side walls 22 and 22' (Figure 3) depending therefrom, while'there is an end wall 23 (Figure 1) at the front end of the arm.

The ear portions 27 and 27' (Figure 2) of the walls 22 and 22' at the rear end of the arm 20 are recessed to provide L-shaped slots 28 having legs 29 and 30 (Fig. 1). Each supporting post 25 is provided with a pin 31 which has its ends extending outwardly providing trunnions 32 and 32' to enter the slots 28. The arm has smoothparallel faces along these ear portions 27, 27' and the inner surface of" its walls 22 and 22', while the post 25 is square and of substantially the same dimension as the distance between the inner surface of the arms. Thus, when the arm is positioned on the post 25 with its pin 31 in the slots, it will hold the arm in a plane at right angles to the axes of the bottom rolls while it may have a hinging action upwardly in this plane. It may be'swung upwardly about the axis of the pin 31 while also sliding the pin from the portion 29 of the slot to the portion 30 of the slot so that the arm may be swung upwardly while the surfaces of the walls 22 and 22' will engage opposite parallel surfaces of the post 25 and guide the movement of the arm in its hinging action about the .pin 31. Thus, the arm is held against rocking lengthwise of the rolls although it may swing toward and from the rolls. I In order to hold the'arm in its upper position as shown in Figure 9, a pin 33 passes through the post 25 and,

protrudes outwardly beyond the arm to engage a notch 34 in the ears 27 of the arm 20 so as to latch therewith as shown in Figure 9 and hold the arm in raised position. A unit sub-assembly carried by the arm is designated and 9) and which converge toward each other providing a narrow mouth 52 so as to retain the reduced portion 18 of the arbor of the back top roll in position. We have found it convenient, however, to provide the lip 50 rigid with the member 45 merely extending downwardly therefrom and against which the arbor may bear if necessary, while we have made the lip 51 in the form of a wire spring and secured it to the member 45 by a screw 53 which will permitof sufficient resiliency'so that the arbor may be sprung into or out of the bearing as desired and yet will 23 of the arm and also has a bearing in the wall 59 generally 35 and shown in perspective in Figure 10, which 7 comprises a block 36 having a threaded hole 37 which may receive a screw 38 (see Figure 1)'passing through a slot 39 in the. arm and engaging the threaded opening 37 in the block 36' so as to adjustably mount it in the arm.

which is carried by the opposite walls 22 and 22 of the arm. By rotating this screw 58 by means of its head 62 c which is slotted, the positionof the top front roll may be adjusted longitudinally with reference to the arm. By the adjustment of this roll and the back roll, the proper alignment with the bottom rolls may be obtained. The screw is circularly grooved at its end at and held in position by spring ring 61 and its 'head 62 so that while it is rotatably mounted in the walls 23 and 59, it cannot be' accidentally withdrawn therefrom. a j.

Pressure is applied to the top roll through the arm by "ni'e'ansof a stirrup designated generally comprising a shank 'portion-66'which is bifurcated at its upper end providing arms 67 and 67' each with a book 68 and 68'. The stirrup ;65 has-its-shank formed in various sections.

' Thus, there is a section'll l which will rock freely. through ithe elongated'narrow slot 69, while at either side'of this This block carries a pin 40 at right angles to the screw hole 37 upon which there is pivotally mounted a threaded shaft 41. At one end of this shaft a bearing-carrying member 42 is threadedly mounted which may be adjusted as to position by further screwing the member 42 on the shaft. This member carries a synthetic resin bearing 43 which may be formed of some low-friction material and is held in position in the bearing member 42 by screws 44. V 7

On the other side of the pivot of the shaft 41 there is a bearing-carrying member 45 which is also threaded on to the end of the shaft'and which may be adjusted as to position by screwing the same at a different distance on to'the shaft. This bearing-carrying member also has mounted in it a bearing 46 which may be of some nonmetallic low-friction material The members 42 and 45 may be relatively adjusted with reference to the block 36 by removing the block from the arm and threading these along the shaft at diflerent distances thereon and then repositioning this sub-assembly in the arm. A spring 47 is mounted on a pin 48 secured to the arm and bears upon the arm and also upon the bearing member 42 as shown at 49 so as the shaft counter-clockwise, as seen in Figure 1, about 'its pivot 46. The shaft 41 is fiat on opposite sides of also held by screw -44'.

to tend to swing shaped section; the shank is twisted so as to provide sec- 5 through a slot 69 in the portion 70 of the frame and has -a foot near the roll stand beam 10 designated 71 which -is threadedly adjusted on to the end of the stirrup as an so that the length of the stirrup may be varied to accommodate a change in the size of the rolls dueto 0 butfing. This foot is in close proximity to the rail 10 so that a small downward movement will permit it to rest "uponthe rail 10 as in Figure 5. A fulcrum 73 is adjustably the shaft at 41' Each of these bearings has parallel' mounted by means of threaded shank 74 and an opening a 75 in the beam 10 to be engaged by the book 76 of the lever 77 which passes through a slot 78 of the stirrup to engage the same as at 79 so that whena weight 80 is a plied by hanging the same in a hook 81 of the lever,.tlie stirrup will be urged downwardly.

The books 68 of the stirrup extend to a position in close proximity to shaft 82 (Figure 3) the opposite walls of the arm 20 and carries cranks 83, 83'

which in turn carry trunnion pins 84 '84'extending out- -wardly therefrom, which pins serve asa catch means and are adapted to engage the hooks 68, 68.'.. Between the 5 walls 22 and 22' and fixed to this shaft 82 there is a gear 85, and in order to turn this gear 85, we have provided a gear 86 which meshes therewith and which gear 86 is mounted on a shaft 87 which extends through the walls 59, and 23 toa location outwardly of the arm and is there 70 provided with'a head 88 of such shape that it may be while at the-same time urging it toward the bottom roll 'when pressure is applied thereto. s 1 The bearingjmember 45 has apair of lips 5Q and.51 extending downwardly from the member 45 (Figures 1 readily engaged by a wrench or handle so that the shaft may be turned to in turn rotatethe shaft 82 through the gears 86 and so that the pins 84, 84' (see also Figure 4). may be. rotated from a position shownin full linesiin 75 Figure 11 upwardly'and then downwardly .to a location tron 112 to better support the'arms 67, 67 and section 40 113 which supports the broadened portion 114 having which extends through shown in dotted lines at 89 (Figure 11) or as shown in Figure 9, which is ina position-"- to disengage the pins from the hook, and when so disengaged from the hook, a spring 90 will force the stirrup rearwardly so that the book will clear the pins 84, 84, allowing the arm to beswung upwardly to the position shown in Figure .4.

In order that the gears 85"'and 86may be properly aligned, we have mounted a sleeve 9I1on the shaft82 by-reason of its ends abutting the wall '22 andtthehgear 85,. will maintain the gear 85'in the .desiredlposition, while asimilar sleeve 92' on the shaft 87 and located with its ends abutting the wall 59 and the gear 86 will maintain the gear 86 in its desired position. The gear 86 may abut at its forward end the bearing 91 toalso assist in keeping it in. position.

Pressure is applied to the arm 20,-which by reason of the vertical slot 29 is free to move at its rear end vertically. The pressure is applied back of the location of the front rolls, and accordingly the arm will tend to pivot about the front roll so that there will also be pressure applied on the pivot 40 which carries the upper bearings which press upon the back rolls and intermediate rolls. Thus, there is a distribution of pressure as applied by the stirrup between the front, back, and intermediate rolls, and the arm 20 is free to move upwardly or downwardly by reason of the slot 29 at its back end, allowing free distribution of pressure on the rolls themselves. This movement also permits of pressure being applied regardless of the size of the rolls, which may vary due to bufi'lng, which makes them smaller and occurs for truing them up after they have been in use.

The arm 20 also carries a pair of spring fingers 93 and 94 which are L-shaped in cross section and are held in position by a screw 95. These spring fingers are rolled over the outer ends, and one is longer than the other so that a shaft 96 of the front clearer roll 97 may be snapped into position with its surface engaging the top front roll, while a similar shaft 98 of the clearer roll 99 may be snapped into position between similar fingers for engaging the back top roll. By this arrangement the clearers as well as the back and front top rolls are mounted on the arm and will be moved upwardly when the arm is moved upwardly and will be moved from the frame when the unit assembly of the top rolls is removed from the frame.

The intermediate roll assembly is designated generally 14 and comprises a pair of end plates 100 connected by a platform 101 which plates are swivelly mounted upon an intermediate bottom roll 102 which extends through the frame similar to the bottom rolls 12 and 13. The plates 100, however, are spaced only slightly greater than each cot of the top roll and are notched at 106 so as to receive individual intermediate top rolls 103. A belt 107 extends about the intermediate top roll 103 and about a bar 108, while another belt 109 extends about the intermediate bottom roll 102 and a bar 109 providing contacting belts or aprons through which the yarn extends and is carried from the back rolls to the front rolls. This entire intermediate roll assembly will rock about the bottom roll 102 when no yarn is in the machine and the top roll assembly unit is lifted, but we prevent this action by providing on the stirrup 66 an arm 105 which will engage the platform 101 which extends between the plates 100, this arm engaging this platform 101 and holding the intermediate roll assembly from rocking about the roll 102 when the stirrup is in the lowered position as shown in Figure so that its foot 71 engages the beam 10.
